Abstract
The invention discloses a spring type valve seat of a stop valve, and belongs to the technical field of valve seat assemblies. The invention adopts the following technical scheme: the utility model provides a stop valve spring disk seat which characterized in that, includes disk seat ring, spring assembly, it has the recess to open on the disk seat, the disk seat ring pass through spring assembly fixed set up in the recess of disk seat. The valve seat ring and the valve clack can be matched and ground in pairs, and the pretightening force of the spring can be guaranteed according to the pressure grade.
Description
Technical Field
The invention relates to a spring type valve seat of a stop valve, and belongs to the technical field of valve seat assemblies.
Background
The stop valve has improved structure along with the continuous improvement of the characteristics of the used materials, and the service life of the stop valve is also continuously prolonged. However, in the industrial continuous production process, the valve seat assembly of the stop valve is subject to temperature change, pressure change, scouring, abrasion, and particle accumulation, extrusion and corrosion of fluid media, so that the valve seat assembly is subjected to pitting, defect, indentation and depression, and further, the problem of internal leakage caused by poor sealing of the joint surface is generated, and the problem becomes one of the reasons influencing the service life of the stop valve.
Disclosure of Invention
The invention aims to provide a spring type valve seat of a stop valve, which is convenient for the disassembly and the assembly of the valve seat of the stop valve from a valve body and solves the technical problem that the whole valve can only be scrapped due to high maintenance cost when the sealing surface of the valve seat has serious defects in the prior art.
The invention adopts the following technical scheme: the utility model provides a stop valve spring disk seat which characterized in that, includes disk seat ring, spring assembly, it has the recess to open on the disk seat, the disk seat ring pass through spring assembly fixed set up in the recess of disk seat.
Preferably, the spring assembly comprises an upper spring ring, a lower spring ring and a spring.
Preferably, the valve seat ring comprises an outer ring and an inner ring, and the upper surface of the outer ring is propped and fixed on the valve body by the elastic force of a spring and is extruded on the valve body.
Preferably, the outer race, the inner race and the bottom surface of the seat ring are each positioned in a groove of the seat.
Preferably, the valve seat ring is arranged in pairs with the valve flap.
Preferably, the radial dimension of the valve seat ring is equal to or greater than the radial dimension of the valve flap.
The invention achieves the following beneficial effects: (1) only the valve seat assemblies need to be replaced in pairs after the valve seat rings are damaged; (2) the valve seat ring and the valve clack are matched and ground in pairs, and the pretightening force of the spring can be guaranteed according to the pressure grade.

Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The invention provides a spring type valve seat of a stop valve, which is characterized by comprising a valve seat ring 4 and a spring assembly, wherein a groove is formed in the valve seat, and the valve seat ring 4 is fixedly arranged in the groove of the valve seat through the spring assembly, as shown in figure 1.
The spring assembly comprises an upper spring ring 1, a lower spring ring 3 and a spring 2; the valve seat ring 4 comprises an outer ring and an inner ring, and the upper surface of the outer ring is propped and fixed by the elastic force of a spring and is extruded on the valve body; the outer ring, the inner ring and the bottom surface of the valve seat ring 4 are positioned in the groove of the valve seat; the valve seat ring 4 is configured in pairs with the valve clack; the radial dimension of the valve seat ring 4 is greater than or equal to the radial dimension of the valve flap.
